Comment 29 for bug 205496

Same here, Canon CanoScan N 650U.
Works if I change the permissions of the device node:

$ sudo chown root:scanner /dev/bus/usb/003/003

the output of lshal is attached (just the part about the scanner though.
ck-list-sessions gives no output. I guess this is because I don't use kdm or gnome. I use dwm as a windowmanager and use no loginmanager at all (just login on virtual terminal and do startx).
